fix bug when test_fail is called via a do statement

[nnutter]

test_fail used $0 as the filename instead of the filename reported by
caller. Under normal execution these would be the same but if the test
is executed by a do block then these would no longer be the same.

Thanks for the patch and the great tests!

Fascinating. I'm kinda curious how that came up.

Our tests are very slow so we wrote TestTracker to record which module
a test uses so we can "guess" which tests need to run based on what code
changed. It is just a quick hack that wraps prove and provides a script to
use for prove's test executor. It could probably be a prove plugin but it
works well enough for now. It wraps each test by executing the test in a
do block which additional logic to track the modules loaded in %INC.

Do you want to backport this to 0.98 too? I can make the patch if you like.

Up to you.
